I do not like to do advertising around microdrum… but since I have recently updated my project, I thought it would interest someone. I made an app for iPhone / iPad that lets you control the microdrum module (certainly more comfortable than any button of the current modules) but also plays the samples loaded: http://microdrum.altervista.org/blog/microdrum-app-on-ipad-video/ All your suggestions would be greatly appreciated, I’m spending much time in this project.
